CONTINUOUS-INTEBFOLD PACKET.

application mea my 22, i925. serial mi. unisal a This invention relates to record supplies for use in making manifold inscriptions, andwith respect to its more specific :Eeatures, to a record supply packet wherein the 5 record strips are separate from each other and of such lengththat a large number of printed forms, subsequently to be filled-in,

may be printed thereon, and successively, drawn or fed to position for inscription, as

in for instance, to inscribing position in a types writing machine or the like, succeeding forms being drawn from the packet to inscribing position in the machine by drawing the forward portions of the strips.

One of the main objects of the invention is the provision of a practical and efficient record supply packet ofthe character referred to,l by'use of which it will be unnecessary for the operator to perform carbon interleaving operations between inscribing operations on successive forms, or touse cai'bons independent of the packet, and in which a great length-of a separate carbon strip may be employed and its whole length e utilized by the successive drawing operations without injurin the carbon strip or placing on any part o the length ofthe carbon strip drawing tension sufficient to part the carbon strip, the packet also being so' constructed that any of the carbon-strips `or any portion of the length of any number of carbon strips that may be used is readily accessible and may be convenientl adjusted and manipulated relative `to 4t e record strips without dismembering the packet.

By the present invention there is provided a packet for use in typewriting machines which is instantly available for making a succession of manifold copies,as for payroll checks, letterheads, purchase orders, in'- voices, bills of lading, and the like, all without the use of carbons other than that contained inthe packet itself. The packet consists of a plurality of stri stripbeing'an'ori al an having successive forins printe lthereon, and theother strip or strips serving as records or dupli- -cates therefor. The stripsjare super-posed one on the other' and oldedin 'zig-zag formation to form a packet which readily unfold as the strips are fed asa continuous -composite web throughl a typewriting machine, lwhere the printed forms are filled in. f As will beperceived further on, there is provided a continuous strip of carbon paper of paper, one

which separated from the record strips and which is interposed between the original and the duplicate record strips and in-v f terfolded therewith so as to be retained between the record strips and to-be advanced `therewith to inscribing position, and so as always to li e`in position such that a record of the typing or filled-in matter will be transferred to the duplicates during the typing operation. i For tliepurpose of more clearly describing the invention, reference is made to the accompanying drawing forming a part of this specilication and drawings, in which- Fig.- 1 is a perspective view of a packet. Fig. 2 is a plan view of the duplicate strlizp.

ig. 13 is a plan view of the carbon strip. Referring to the drawings'in detail and particularly to Fig. 1, A indicates in general a packet consisting of a plurality of separate, continuous stripsof paper such as indicatedat B, C, and D. These strips are super-posed one on the other as shown and are folded i-n zig-zag fashion along the lines indicated at 2 and 3 so that a packet formation is obtained. The uppermost record strip-indicated at B will be the original strip, the strip C the transfer-strip, or stri of cirbon paper, "and the sheet D the duplicate s ri figlie original strip 'B has a longitudinal series of forms printed-thereon as shown; such as check blanks, letter heads, or what-` ever tiie case may be, as indicated at 4, and the blank spaces are preferably lled in by passing the strips as a composite continuous iveb'thiough a typewr'iting machine. Forinstance, it pay roll checks 4 are to be filled out, three or more checks may be 'printed on each fold in successive order as indicated in Figl. The checks are filled out during the typing operation and a transfer is made, by thefcarbon paper, on the duplicate strip indicated at'D. The original strip B is per- 100 forated along the lines 5 to weaken the same and to permit the checks toA be easily separated or torn apart and the duplicate is similarly perforated along the lines 6 to per- .mit the duplicates similarly to be separated from each other if desired. "The several strips are also similarly weakened as by being perforated along the parallel lines of transverse fold indicated at 2 and 3,' and the strips may thus first be yseparated in sheet 1'10 sections and then later separated into individual checks and du licatesif desired. The original strip and t e duplicate may. thus have two sets of perforations, those indicated at 2 and 3 and the intermediate perforatons shown at- 5. The'carbon strip C is, however, only perforated along the lines 2 and 3 (see Fig. 3) and thus the carbon sheet sections or folds may after use in the packet,

strips, so that the lower folds of the three strips are retained against movement relative to each other, while upper folds thereof are being drawn to writing position in the machine. By the restraint against resultant relative movement, defacement on account of l smutting of the record strip bythe carbon strip is n `the restraint against relative movement 1nthe rgely avoided and, it will be noted,

creases the deeper the folds are located in acket, on account of. the increased weig t of acket material above. The number ofl fol s of the packet may be-as man y as desired, there being practically no llmit to the length of strip which may be ems ployed. It will be noted, however, that although the carbon strips may be very long, all the drawing strain on the carbon strip 1s confined to the relatively short length running from the upper fold of the packet to the platen ofthe typewriter, the lower folds of the carbon strip being entirely free of the drawing strain. Hence, by the construction described, even though' the transfer strip be ver?,7 weak, an even though the transfer material thereon readily may come off, the arrangement ofthe transfer strip in the packet largely provides against smutting of the record strips and permits theemployment' of a very long, continuous-transfer strip between and in manifold contact with the record strips, and/the consumption of its entire len th by the successive drawing operations, w ereas the strain on the strip due to the successive drawing' operations may be 'relatively light and much lighter than would be required to advance Ithe weight of the whole length of transfer `strip at each of the successive drawing operations.

As no one strip is directly connected to another, they may readily be separated for examination, adjustment and the like,` at any l point in the packet. Should the relatively weaker transfer strip be accidentally divided at any point-in the packet, the parted section will be retained in place and -will be advof a dark color its position throughout the packet may readily be traced. Should it be out of registry the packet may be opened up at the precise point and the carbon sheet adjusted in either lateral direction required. As the lines of foldy in thepacket are all parallel to each other, the carbon strip runs LII free from the packet to writing position and there is lpractically no chance for it to bev come entangled andtorn as it feeds from the packet, notwithstanding it may be-of great length.

A packet of thischaracter is exceedingly useful when filling outpay roll checks, bills oli-lading, invoices, and the like, as the original, the carbon, and the duplicate are fed by the operator as a composite continuous -web through the typewriter as the .checks or other work are filled in. This is obviously an advantage as it eliminates the necessity, on the part of the operator, of inserting-seplarate sheets and the carbon and aligning t e `same for each operation. The inserted continuous carbon strip is also 'a time saver and important as iteliminates the necessity of re-inserting a carbon sheet for each successive manifold set of forms. It should also be noted that when the originals and duplicates are separated yalong the fold linesa by-product is obtained; to-lwit, the'4 carbon sheets, which may be re-used forother purposes whenever desired. The user of a packet of this character thus has all the carbon paper required for the llingin of thepacket and obtains as a by-product a number of carbon sheets to take care of other work.

Having thus described my invention, what I claim and desire to secure by Letters Patent isf 1. A packet for use in making manifold ment relative to lower folds of said record strips Iand free of drawing strain consequent from drawing upper folds'of said transfer.
